Rose plant

ABSTRACT

A new variety of rose plant of the hybrid Floribunda class, being a hardy outdoor seedling of the bush type, well adapted for mass display because its blooms are abundant, most of them being carried in clusters of as many as five or more to a stem. Flowers are from 21/2 to 31/2 inches across, and have from 32 to 40 petals and from 0 to 5 petaloids. The flower coloration is a distinctive purple-red as hereinafter described in detail.

This invention relates to a new variety of hybrid Floribunda rose. Theplant is a hardy bushy outdoor seedling grown mainly for gardendecoration. It was hybridized and asexually reproduced by Reimer Kordesin Sparrieshoop, Holstein, West Germany, having as its seed parent"Zorina" (Plant Pat. No. 2,321) and for pollen parent "Silver Star". Theplants described herein have been asexually reproduced by budding inOntario, Calif., from budwood of the new variety. The new variety holdsits distinguishing characteristics through succeeding propagations bybudding.

The plant bears its flowers usually three to five or more in irregularrounded clusters, on strong medium to long stems. It blooms freely toabundantly outdoors, and nearly continuously during the growing season.The blooms have a slight tea fragrance.

This rose cultivar may most readily be distinguished from its seedparent, Zorina, by the following combination of characteristics:

Whereas Zorina bears buds and flowers of grenadine-red coloration, thenew rose bears buds and flowers of a purple-red coloration essentiallyas more fully described below, and as illustrated herein.

The new cultivar bears flowers with significantly greater petalage (from32 to 40) than Zorina, which bears flowers with about 25 petals.

Zorina was designated as a cultivar for greenhouse cut flower usage,whereas the new rose is strictly for garden decoration.

This new rose cultivar may be distinguished from its pollen parent,Silver Star, by the following combination of characteristics:

Whereas the new cultivar bears buds and flowers of a purple-redcoloration, Silver Star bears buds and flowers of a light lavendercoloration.

Silver Star has large open flowers of 5 inch diameter, whereas the newcultivar has significantly smaller open flowers of 21/2 to 31/2 inchdiameter.

Whereas Silver Star is classified as a hybrid Tea rose, the new cultivaris classified as a hybrid Floribunda.

The accompanying drawing illustrates the plant in color, and shows theflowering thereof from bud to full bloom.

Throughout this specification, color names beginning with a small lettersignify that the name of that color, as used in common speech, is aptlydescriptive. Color names beginning with a capital letter designatevalues based upon the Nickerson Color Fan, put out by Munsell Color Co.

BUD

The peduncle is average length to long and of average caliper, erect andstiff, almost smooth, but with some stipitate glands. The color isbetween Moderate Yellow Green, 5GY5/6, and Moderate Yellow Green,2.5GY5/5.

Before the calyx breaks, the bud is medium in size, for Floribundaroses, of medium length, ovoid, with a few stipitate glands on thesurface of the bud. There are usually slender foliaceous parts extendingbeyond the tip of the bud equal to one-fourth or more of its length.

As the calyx breaks, the color is between Dark Red, 2.5R3/7, and DeepPurplish Red, 10RP3/10. The inner surface of the sepals carries a finetomentum. Margins are lined with stipitate glands.

As the first petal opens, the bud is of average size for Floribundaroses, of medium length and ovoid. The color on the outside of the petalis between Moderate Red, 2.5R4/10, and Strong Purplish Red, 10RP4/12.The color on the inside of the petal is between Moderate Red, 2.5R4/10,and Strong Purplish Red, 7.5RP4/11. At the basal attachment zone on boththe outside and inside of the petal, the color is between white andBrilliant Yellow Green, 2.5GY9/8. The bud opens up well and is notprevented from opening by cold, hot, wet or dry weather.

BLOOM

When fully open, the bloom is average size for Floribunda roses, beingfrom 21/2 to 31/2 inches in diameter. The petalage is double, with from32 to 40 petals, plus from 0 to 5 petaloids arranged regularly. In form,the bloom is cupped at first, the petals remaining at first somewhatcupped with tips reflexed outward, becoming later at maturity moreloosely cupped, with tips reflexed outward.

The petals are of medium thickness, with inside slightly satiny andoutside shiny to satiny. The outside petals are broadly obovate, withapex flat. Intermediate petals are also broadly obovate, but with apexrounded. Inside petals are obovate with mucronate apex. The colors maybe modified by being shaded and/or washed or tinted with other colors.

The description which follows is of the color values noted in a flowernewly opened in the month of June. The plant had been grown outdoors inOntario, Calif.

All petals, outside, intermediate and inside, were of the samecoloration. The basal attachment zone was between white and BrilliantYellow Green, 5GY9/8. The remainder of the outer surface was betweenDeep Purplish Pink, 7.5RP6/12, and Strong Purplish Red, 7.5RP4/11, whilethe remainder of the inner surface was between Deep Purplish Pink,5RP6/10, and Strong Purplish Red, 7.5RP4/11.

The following description is of a rose that was open for three days. Ithad been grown outdoors in the month of June, in Ontario, Calif.

All petals, outside and inside, were of the same coloration. The basalattachment zone outside and inside was between white and BrilliantYellow Green, 5GY9/8. The remainder of the outer surface was near DeepPurplish Pink, 5RP6/10, while the remainder of the inner surface wasbetween Deep Purplish Pink, 5RP6/10, and Moderate Purplish Red, 5RP5/10.

The general color effect of the newly opened flower is between DeepPurplish Pink, 5RP6/10, and Strong Purplish Red, 7.5RP4/11. After beingthree days open, the bloom gives a general color effect of between DeepPurplish Pink, 5RP6/10, and Moderate Purplish Red, 5RP5/10. The petalsdrop off cleanly, and are not particularly affected by cold, hot, wet ordry weather.

The flower on the bush in the garden persists for from 4 to 5 days inthe month of June, in the locality named. Cut roses grown outdoors andkept at living-room temperatures will last from 3 to 4 days in the monthof July.

REPRODUCTIVE ORGANS

There are many stamens, arranged regularly about the pistils.

I claim:
 1. A new and distinct variety of Floribunda rose plant,substantially as herein shown and described, and being especiallycharacterized in the distinctive purple-red coloration of its blooms,and in the abundance of its dark green glossy foliage, which covers theplant during the growing season.
